Renewable/Non-renewable Resources Activity It would be useful to have more teacher notes on each slide Adapted from UNC-Wilmington curriculum

What is a renewable energy resource? Renewable energy is natural energy which does not have a limited supply. Renewable energy can be used again and again, and will never run out. Types: Biomass Hydro-electric Geothermal Solar Tidal Wave Wind Wood

What is a non-renewable energy resource? An energy resource that is not replaced or is replaced only very slowly by natural processes Fossil fuels are continually produced by the decay of plant and animal matter, but the rate of their production is extremely slow, very much slower than the rate at which we use them. Types: Coal Oil Nuclear Natural Gas Tar Sands and Oil Shale

Objectives Understand how population relates to energy resources Evaluate problems related to resource availability Discover differences between renewable and nonrenewable energy resources Learn strategies to prevent resource depletion

Activity Preparation The class will be divided into groups of 4. Each group will need a bag with 16 pieces of popcorn, 4 paper towels, and a pencil and paper. Teacher will need the bag with leftover popcorn to replenish the “used resources.”

Part 1: Renewable Resources Activity Each team begins with 16 pieces of popcorn. Each student must take at least 1 piece of popcorn per round to survive, and may take as many as he/she likes. One student per team records the number of pieces each team member takes per round, and the number of pieces remaining for the team. The resource is then “renewed” by half ( if there are 8 remaining pieces after round 1, the teacher will add 4 more pieces to the bag for round 2). 6 rounds are played in this manner. The object of the game is to have the most pieces of popcorn per team member after the final round. QUESTION: Do the students know the rules ahead of time – e.g. that if they take less up front, there will be more replenished?

At the end of the game, discuss different strategies used by teams: Some may die because they’ll consume too much of the resource early on Others may take one piece at a time and build up a store by the end Others may take more throughout but will always keep enough in reserve to be sufficiently renewed

Part 2: Non-Renewable Resources Activity Students each pick up a slip of paper from a bag (there are 4 “1st generation”, 6 “2nd generation”, 9 “3rd generation,” and 14 “4th generation” slips) Teacher goes to the front of the classroom with a bag of popcorn, and leads a brief discussion of what it means when one generation finds a resource and how future generations are affected by it. 1st generation students then come up and take as much popcorn as they want back to their seats. 2nd generation students then do the same, followed by 3rd and 4th generations. If 1st generation users consume too much of the resource in their lifetime, very little will be left for the 2nd generation to use, and even less for the 3rd generation. Non-renewable resources are finite and will not be recreated on a human time span. We only have a limited number of resources to use, so we must use them with future generations in mind.

Teacher and students should then discuss: how the students acted in “using” the resource any waste that occurred (popcorn dropped on the floor) whether any thought was given to students coming afterwards if there were protests from other students the degraded quality of popcorn towards the end (everyone’s hands were in it before, and it’s been crushed into smaller, less desirable pieces Made changes on this slide

Follow-Up Questions Categorize the following as renewable, non-renewable or perpetual resources: A field of corn Oil in the Arctic tundra Coal in the Appalachian mountains Sunshine Trees in a forest Tuna in the ocean Sand on a beach A breeze over the Texas plains Water in a river Which resources would continue to be available no matter how much people used them? Under what circumstances would a renewable resource not be renewable? Have we defined perpetual resources? I don’t even know how to classify Sand on a beach – if you’re a glassmaker it’s a nonrenewable source, isn’t it?

Follow-Up Questions What could be some effects of population growth, natural disasters, disease, and advanced technology systems on resource availability? What are some advantages and disadvantages of using renewable resources in place of non-renewable resources? List as many renewable resources as you can find in your classroom. List as many non- renewable resources as you can that are found in your classroom. Provide examples here (and explanations in the case that the examples might be subjective) of answers to each question
